find 2 numbers whose sum is 36 and diffrence is 10
Answer:
23 and 13
Step-by-step explanation:
can you help me with my latest answer too??i'm on a time limit rn
Answer:
13 and 23Step-by-step explanation:
let 2 number be x and y
x + y = 36 ---- equation ( 1 )
x - y = 10 -----equation ( 2 )
from ( 1 ) and ( 2 )
2y = 26
y = 13
putting value of Y in equation ( 1 )
x + y = 36
x + 13 = 36
x = 36 - 13
x = 23

How do you write the equation in slope intercept form given (2,2) and (0,-2)?
Answer:
y = 2x - 2
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m is the slope, and b is the y-intercept.
y = mx + b
First we find the slope, m.
slope = (difference in y)/(difference in x)
It does not make a difference which point is first and which point is second in finding the differences, but you must do the x- and y-differences in the same order.
slope = (-2 - 2)/(0 - 2) = -4/(-2) = 2
The slope is 2, so m = 2, and now we have:
y = 2x + b
We need to find the value of b, the y-intercept.
We use one of the given points. Let's use (2, 2). We plug in 2 for x and 2 for y and solve for b.
2 = 2(2) + b
2 = 4 + b
-2 = b
b = -2
Now that we know the y-intercept is -2, we substitute b with -2.
y = 2x + b
y = 2x - 2
Answer: y = 2x - 2

what is the measure of angle x?
Answer:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.
Step-by-step explanation:
Step-by-step explanation:
all Δangle sum = 180°
so, therefore
93° + 52° + x° = 180°
145° + x° = 180°
x° = 180° - 145°
x° = 35°
MARK ME BRAINLISTWhich of the following is equivalent to 4x - 3y = 12 ?
y = -4/3x - 4
y = 4/3x + 4
y = -4/3x + 4
y = 4/3x - 4
Answer:
y = 4/3 x - 4
Step-by-step explanation:
The slope-intercept form of the equation of a line
The equation of a line can be expressed in several forms. One of them is the slope-intercept form:
y = mx + b
Where
m = slope
b = y-intercept
We are required to convert the equation of the line:
4x - 3y = 12
It can be done by solving for y.
Subtracting 4x:
- 3y = - 4x + 12
Dividing by -3;
y = 4/3 x - 4

Answer:
We know that g(n) = n + 1
So we need f(n+1)
We know that whatever we give to f it will multiply it by - 3 and add 3 to it so we have to :
(n + 1) × (- 3) + 3 = - 3n - 3 + 3 = - 3n
So choice C is correct

Use algebra to find the point at which the line h(x)=−(3/5)x+(7/5) intersects the line k(x)=(−8/3)x+(404/45).
Answer: the point (3.667, 0.8)
Step-by-step explanation:
We want to find the point at which the lines:
h(x) = -(3/5)*x + (7/5)
and
k(x) = (-8/3)*x + (404/45)
If the lines intersect, then we must have:
h(x) = k(x)
if we write the functions we get:
-(3/5)*x + (7/5) = (-8/3)*x + (404/45)
Now we need to solve this for x.
-(3/5)*x + (8/3)*x = (404/45) - (7/5)
(8/3 - 3/5)*x = 404/45 - 63/45 = 341/45
(40/15 - 9/15)*x = 341/45
(31/15)*x = 341/45
x = (341/45)*(15/31) = 3.667
Now we can input this value of x in the functions to get the output.
h(3.667) = -(3/5)*3.667 + 7/5 = -0.8
Then the point where our points intersect is the point (3.667, 0.8)

Find value of x and y
Answer:
x = 60
y = 80
Step-by-step explanation:
x° + 120° = 180° (interior angles on the same side of transversal)
x° = 180° - 120°
x° = 60°
x = 60
x° + y° = 140° (alternate angles)
60° + y° = 140°
y° = 140° - 60°
y° = 80°
y = 80
The measure of angle ∠x is 60° and ∠y is 80°.
What are Alternate Interior Angles?Alternate Interior Angles is defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
Since angle ∠x and ∠120° are interior angles on the same side of transversal.
So, x° + 120° = 180°
x° = 180° - 120°
x° = 60°
x = 60
Since angle ∠x° and angle ∠y° are alternate angles
So, x° + y° = 140°
Substitute the value of x = 60 in above equation,
60° + y° = 140°
y° = 140° - 60°
y° = 80°
Hence, the measure of angle ∠x is 60° and ∠y is 80°.
